Zusammenfassung:	The utility model discloses a motorcycle fuel quantity LED display instrument including a motorcycle fuel quantity display instrument, a fuel tank connected with the display instrument, and a motorcycle power supply, wherein the inside of the fuel tank is provided with an oil level sensor, a CPU chip is arranged inside the display instrument, the oil level sensor is in signal connection with the CPU chip via a resistance voltage dividing circuit, the display instrument is further provided with a plurality of LED display lamps for displaying different colors, and the CPU chip is in signal connection with each LED display lamp via a voltage comparison circuit. By adopting such a motorcycle fuel quantity LED display instrument, the CPU chip receives the signals from the oil level sensor, and the corresponding LED display lamps respectively display yellow, green, and red based on the different residual oil levels in the fuel tank. The use of the LEDs can effectively prevent the temperature rising caused by a poin
